OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 553,971, dated February 4, 1896.

Application filed March 8, 1895.

T0 all whom it may concern:

Be it known that 1, CHARLES C. TYLER, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Oil-Cups, of which the following is a specification.

This invention relates to lubricators or oilcups, the object being to provide, in the one structure, simple-and elfective means for the exclusion of dust, dirt, and other foreign substances from the interior of the cup and the bearing to which the device may be applied, and a cap and valve for permitting the ready refilling of the oil-cup and for securely holding the oil therein.

In the drawings accompanying an d forming part of this specification, Figure 1 is a longitudinal section of the oil-cup with the oil-feed opening shown closed. Fig. 2 is a similar view showing the cap and valve with its opening registering with an opening in the top plate of the oil-cup. Fig. 3 is a plan view with some parts broken away and in section for more clearly showing the cap and valve, top plate, and interior parts; and Fig. 4 is a longitudinal section of one modified forni of oil-cup.

Similar characters designate like parts in all the figures.

My improved oil-cup embodies effective means for the exclusion of dirt and other foreign substances from the working parts of an apparatus, through the medium of a revoluble resilient cap and valve, which is to be rotated or turned on the top plate of the oil cup or receptacle for permitting the introduction of a lubricant into the oil-cup and for securely holding the same therein.

The improvement also embodies elficient means for preventing both lateral or rotatable niotion or upward displacement of the cap and valve.

The body or main portion is designated by A, and has an interior chamber or receptacle d for the oil or lubricant, which chamber -may be of any preferred form.

In Figs. 1 and 2 the oil-cup is shown proserai No. 541,005. (No model.)

vided with an enlargement or bulge 1, which forms a seat 2, to rest upon or against the body, shiftbearing, bicycle hub, or other part to which the device maybe applied, also a screw-thread 3 for retaining the oil-cup in position for use.

The oilcup body or receptacle which is shown open at its lower end and in Figs. 1 and 2 is further shown as having' a longitudinal bore 4, that is usually provided with a wick (not shown) for feeding the lubricant to the journal or shaft. The top plate of the main or body portion A is designated by B, and has, in Figs. 1, 2, and 3, a downwardlyprojecting flange or portion 7, preferably immovably seated in the body or main portion in some suitable manner. An outwardly-extending circumferential flange or rim is shown at 8, it resting on the upper edge of the part A. This flange or rim S projects slightly beyond the outer face of the main or body portion A and forms a guideway for the cap and valve.

The top plate B is shown provided with a feed-opening 9, through which the lubricant is fed orintroduced from asuitable source (not shown) to the chamber or receptacle a. A concavity or depression `10 is shown in the upper face of the top plate B, which co-operates with and receives a correspondingly-formed convex or raised portion in the lower face of the cap and valve.

The cap and valve is designated.. by C, is constructed preferably of resilient thin sheet metal, and is shown as provided with overturned edges 11 for engaging the circumferential flange or rim 8. This portion 11 projects inwardly for a short distance, which locks the parts together and prevents accidental displacement of the cap and valve. The cap and valve C is also provided, suitably on its outer edge or periphery, with milling 12 or other suitable means to assist in the ready rotation of said cap.

The cap and valve C is shown provided with an opening or hole 13, which, when the oil ,is being introduced into the cup, registers with the opening D in the plate B. This opening 13 is made by being eounterbored, which forms a slight shoulder ll, which engages over or impinges against the opening in the top plate l when the oil is being introduced into the cup, this engagement or impingement preventing rotation, except by hand, of the cap and valve C.

The convex or raised portion hereinbefore mentioned is shown at ll), it being seated, when the lubricant is being introduced into the cup, in the correspondingly-formed depression or concavity il) in the top plate l. A slight exertion of power by grasping the main portion l2 and raising slightly the cap and valve to turn the same will elfect a registration of the openings D and 13 to permit the introduction of a lubricant; or, by reversing this operation, the opening E) will be closed to exclude dirt from the cup. The openin 9 in the top plate l forms an effective valve-seat for the convex portion 10, and the concave portion l() receives the shoulders 1l when closed, this engagement of the parts preventing lateral movement oi the cap by sudden jars or knocks or when the device is on a moving or rotary part. 'hen the lubricant is introduced into the cup, the openings 13 register and the shoulder ll impinges against that of the opening i). the convex portion 10 resting in the eoncavity 1() in the top plate B.

The oil is introduced into the openings J and 13, filling the space it and the bore l, and from thence to the journal or shaft of the machine. A wick (not shown l is generally seated in the tubular portion 5, extending upwardly from the bottom f3, said wiel; assisting in feeding the lubricant to the shaft or journal.

The lubricator or oil-cup, as modified and as shown in Fig. l, is constructed similarlyT to that disclosed hereinbefore, except that I have here dispensed with the tubular portion 5 and the exteriorly-formed enlargement l and the seat 2 formed thereby and make the cup or receptacle A of plain cylindrical form. The mode of operation of this inodiiied form of construction is substantially similar to the one shown in Figs. l, 2, and 3.

The openings 5l and 13 in the top plate B and valve C,resi )ectively, and the concave and convex portions l() and l0 thereof, are shown as eccentric and each equidistant from the centers of the parts l5 and C, so that a rotation of the cap and valve C on the top plate B to fill the cup with oil will insure an accurate registration of these openings 5l and 13 to introduce the lubricant and at the same time permit the seating of the convex portion lO in the concavity ll). ly this relative arrangement of the openings l) and 13 and the convex portion 1U and concavity l() the former Will be seated in the opening 5), which forms a valve-seat therefor, and the shoulders 14 of the opening i3 will rest in the concavity :l

l 1U when the cap and valve C is performing its d ust-excluding function, this engagement i positively locking the parts and preventing rotation of the cap and valve.

As hereinbefore stated, the cap and valve l L is constructed preferably of resilient material, which by reason of its springy nature renders possible the easy disengagement of i the parts to rotate the cap and valve by its convex and shouldered portions being sprung out of engagement with the opening and concavity in the top plate while at the same time as effectively locking the said cap in a predetermined position.

Having thus described my invention, I Claiml. An oil-receptacle consisting of a body having a relatively large chamber extending from side to side of said body, and having an oil-feed opening remotely disposed from the top thereof; a flat top plate extending beyond the body, and forming a cap-receiving flange, and having an opening and a eoncavity therein forming valve-seats; a resilient sheet-metal cap having its edge extending around the edge of the cap-receiving flange for holding said cap in rotatable frictional engagement l with the top plate, said cap having an openi ing adapted to register with the top-plate l opening, and a deflected portion adapted to l rest in said top-plate opening or in said con.- 1 cavity. ,l r2. -in oil-receptacle consisting of a body having a relatively large chamber extending from side to side of said body, and having an oil-feed opening remotely disposed from the top thereof; an independent and normallyl immovable flat top plate extending beyond l the body and forming a cap-receiving flange, l and having a downwardly-extending flange, l substantially at right angles to said top plate, and extending into the chamber of said body, for holding said top plate immovably onto l the body, said top plate having an opening tand a concavity therein forming valve-seats; 1 a resilient sheet-metal cap having its edge exi tending around the edge of the cap-receiving l flange, for holding said cap in rotatable, frictional engagement with the top plate, said cap having an opening adapted to register with the top-plate opening, and a deflected portion adapted to rest in said top-plate opening or in said concavity.
